Unacceptable to be told a network problem can't be solved

It seems like, complaining online is now my last option to get the needed customer care. Never ever have I ever experience such bad service as with Vodacom this past 4 days...to a point where consultants are actually telling me there is nothing that they can do to fix my problem. Since Friday 31 August, my phone's network service has been suspended - everyday I phone Vodacom and they fix the problem, just for the network to cut off at 7pm in the evenings again until the next morning when I can actually get to a landline to phone and ask for a solution experts to fix it again. This is unacceptable to have a cellphone contract that is not working and it is unacceptable for Vodacom to pull up there shoulders and tell me there is nothing that they can do about it. I have been friendly and patient for the past 4 days but I'm actually really fed-up now and will be complaining on every social media and online platform I can find until something gets done about the situation.
